For some reason it is possible that the healthbar object will be set to alpha = 0.5 even while the parent element itself is at alpha = 1. I tried alot of stuff to fix the alpha value. Nothing worked. In the end I decided to create a new healthbar and just hide the default one (but keep it for value reference). That worked out great.

On that note. I had no problems with the frame scaling. That is because I use my own width and create new nameplate art.
